This thesis focuses on different aspects of the lifestyle of Croatian youth, giving us an insight into its structure, social organization, occupations and activities in the period between 1968 and 1990. The peculiarity of Croatian youth was in the influence of the western trends and popular culture infiltrating into the socialist Yugoslavia, which affected their formative years and personal affinities. As a result, Yugoslavia would become a non aligned socialist country whose youth was not lagging behind global trends in any way. On the contrary, becoming an active part of social life, Croatian youth voiced its opinion via youth press, radio and television, in some cases including protests. The most prominent influence of the western popular culture was reflected on the development of the music scene in Yugoslavia, giving rise to generational musicians and bands that would leave a longlasting mark on the lifestyle of younger generations. During its activism, Croatian youth supported ideas of self-managing socialism, Tito and the principle of brotherhood and unity as a path to further growth and development. It generally followed the path and through activism analyzed, criticized and pinpointed the weak spots of the principle or the failure of execution.
